HEATING OR VENTILATING DEVlCE.

SPECIFICATION forming part of Letters Patent No. 515,685, dated February 27, 1894.

Application filed April 27, 1893- fierlal No. d72,069. (No model.)

To all whom it may concern.-

Be it known that I, HARRY P. HUSE, lieutenant in the United States Navy, a citizen of the United States, residing at Annapolis, in the county of Anne Arundel and State of Maryland, have invented certain new and useful Improvements in Heating or Ventilating Devices; and I do hereby declare the following to bee. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in methods of and apparatus forheating and ventilating rooms of houses, railway cars, and other public vehicles, and it consists essentially in causing the products of combustion from a burner or burners to draw impure air from the interior of the room or car, and deliver the same on the exterior thereof; and at the same time to induce convection currents of air from the exterior of the room causing them to ascend and to become heated and to enter the interior of the room. In this manner the impure air, which supports the combustion of the burner, or passes over the equivalent source of heat, is drawn out from the room, and at the same time it serves as a Vehicle for heating the cold air drawn from the exterior and delivered into the interior of the room.

My invention consists further in providing a portable window stove, which may be placed in a window and heat the room at the same time delivering the products of combustion on the exterior of the window.

Reference is had to the accompanying drawings,in which the same parts are indicated by the same letters and figures.

Figure 1 represents an interior View of the bottom of a window, my improved heating and ventilating device being shown as fixed in the wall beneath the said window, the reg ister shown in Fig. 2 being omitted for the sake of clearness in the drawings. Fig. 2 represents a section of the degice shown in Fig. 1, along the broken line a; a: of the said figure. Fig. 3 represents aview of a portable box containing my improved heating and ventilating device, the said box being adapted to be placed under a window sash, when the sash is partly lowered. Fig. 4. represents a section of the device shown in Fig. 3 along the line 3 y of the said figure, and also represents a section of a window sill, and sash partly low" cred, the whole illustrating the applicability of my device as a portable means of heating and ventilating rooms.

A represents the window sash.

B represents the windowsill, provided with the bead b as usual.

0 represents abeam beneath the window, shown only in the construction illustrated in Fig. 2. I

D in Figs. 1 and :2 represents the improved heating and ventilating device permanently fitted in the wall beneath the window, although any other part of the wall would do equally well.

D in Figs. 3 and 4 represents the same device shown in Figs. 1 and 2, except that it is put in portable form.

D shown only in Fig. 4, represents a strip or chock, which may be placed beneath the box D'for lining up the same, and may be attached either to the box or to the window sill, or omitted altogether.

E represents a series of gas burners connecting to the pipe F, and receiving gas by means of the pipe F, controlled by a cockf, 8c

and connected in any suitable way to the source of gas supply.

In Fig 4 F represents a rubber tube leading to the gas fixture, not shown.

\Vhile I have shown a series of gas burners, oil or alcohol lamps, or electric heating coils, or any suitable source of heat supply maybe used.

On the interior of the device D or D, d represents a tortuous channel for the passage of 0 the impure air from the inlet 1 to the outlet 2.

(1' represents a tortuous channel for the passage of the fresh air from the inlet 3 to the outlet 4, which latter opens into the interior of the room.

6? represents a deflecting plate, fixed across the box D or D.

61 represents a tortuous plate made of conducting material separating the impure ascending gases from the fresh ascending air, 1C0 the source of heat, primarily, and later the heat transmitted thereby to the impure gases warms the incoming air passing over the other side of the conducting plate. The route of the impure air is represented by the plain arrows, and that of the fresh air entering the room by the feathered arrows.

d and 01 represent deflecting plates for Keeping the hot air, and the air being warmed as much as possible in contact with the conducting plate d (1 represents a series of passages for the heated air to escape, while the air being warmed passing around these passages 61 which are preferably in the form of metal pipes, becomes further warmed.

d represents a diaphragm closing the upper end of the fresh air passage, and (1 represents a water trough over which the warmed air passes, and is made pleasantly moist. It will be seen that the impure air is drawn out, and the fresh air drawn in by convection cur:

rents, and that by regulating the supply of heat, the heating and ventilating of the room.

may be regulated at will.

A register D (as shown in Fig. 2) or other device for regulating the amount of fresh air passing through the passage d may be provided.

In Figs. 1 and 2, a further improvement is i made in hinging the front 1) of the heater so that the heat from the burners E may be radiated directly into the room.

It will be evident that the front of the device shown in Fig. 4, may be hinged. to open in the same or a similar way. This front D is hinged as at d, and the deflecting piece 61 is provided with a hook d which catches on the stop d in the side of the heater when the said front D is swung open. The flame and hot gases from the burners E will then be deflected forward by the curved plate or diaphragm 01 but the gases will be drawn backward and escape through the pipes d, as when the door d was closed. By this con struction the advantages of an open grate are obtained, and moveover the door D while horizontal may be used as a shelf or table to hold articles to be warmed by the warm air entering through the aperture 4:.

It will be obvious that dampers or other equivalent devices for regulating the flow of the outgoing as Well as of the incoming gases may be added to my improved device.

1. A portable device for heating and ventilating rooms, cars, and like inclosed spaces, comprising a case or box with four'apertures therein, a conducting diaphragm, pipes, and deflecting plates separating said box into two upwardly inclined tortuous passages,cross1ng each other and connected to pairs of said apertures respectively, and a burner situated near the bottom of one of said passages, substantially as and for the purposes described.

2. A portable heating and ventilating apparatus comprising a case adapted to fit in a window and provided with an upwardly inclined passage for the admission of air to the burner and for carrying the products of combustion outside of said window and a second upwardly inclined passage for drawing the exterior air into the interior of the room, a tortuous diaphragm and pipes separating the two passages; and a burner at the base of said case, and opening into said passage for carrying off the products of combustion, sub stantially as and for the purposes described.

3. A heating and ventilating device comprising a case or box provided with two upwardly inclined passages crossing each other therein, the one passage adapted to admit fresh air, the other to carry off the products of combustion, a conducting diaphragm sepaating said passages, a burner in the lower portion of one of the passages, and a swinging shelf normally closing the front of said passage, in front of said burner, and adapted to be swung outward, with means for holding said shelf in the raised position, substantially I as and for the purposes described.

4. A. heating and ventilating apparatus comprising a case or box provided with two upwardly inclined passages crossing each other from either side of said case, the one passage adapted to'admit fresh air, the other to carry off the products of combustion, a conducting diaphragm separating said passages, a burner in the lower portion of one of the ICO passages, an air regulating device and a HARRY P. HUSE.
